Method and system for controlling surround view in a low light environment

A system for controlling a surround view in a low light environment, the system comprising:

• a camera unit including a plurality of cameras that acquire images in at least two directions of a vehicle;
• an image synthesizer configured to synthesize a plurality of images acquired from the camera unit into one image;
• a display unit configured to display the synthesized image in a surround view;
• and
• a controller,
• wherein the controller operates the surround view based on a first frame per second (FPS) value, and
• the controller calculates brightness of each of a front region, a rear region, a left region, and a right region from images received from the camera unit, and operates the surround view based on a second FPS value lower than the first FPS value for each region when the brightness corresponding to the region is less than a first set value,
• wherein the display unit displays selection information of options including FPS priority, brightness priority, and a default setting,
• the controller operates the surround view based on the second FPS value lower than the first FPS value for each region by changing a condition according to the selection information of options,
• the default setting is conditioned on whether the brightness of the image captured for the surround view is less than the first set value,
• the FPS priority is conditioned on whether the first set value is set to be lower than the default setting and the brightness of the image captured for the surround view is less than the first set value, and
• the brightness priority is conditioned on whether the first set value is set to be higher than the default setting and the brightness of the image captured for the surround view is less than the first set value.

A method of controlling a surround view in a low light environment, the method comprising:

• displaying selection information of options including FPS priority, brightness priority, and a default setting;
• operating the surround view based on a first FPS value;
• calculating brightness and determining whether the brightness is less than a first set value;
• operating the surround view based on a second FPS value lower than the first FPS value when the brightness is less than the first set value;
• and
• operating the surround view based on the second FPS value lower than the first FPS value by changing a condition according to the selection information of options,
• wherein,
• the default setting is conditioned on whether the brightness of the image captured for the surround view is less than the first set value,
• the FPS priority is conditioned on whether the first set value is set to be lower than the default setting and the brightness of the image captured for the surround view is less than the first set value, and
• the brightness priority is conditioned on whether the first set value is set to be higher than the default setting and the brightness of the image captured for the surround view is less than the first set value.
